1835: Ramadge's inhaling tube for consumption and asthma

Respiratory therapists are well aware of insentive spirometers (IS) and positive end expiratory (PEP) therapy. You might think these are modern inventnions. You would be wrong.

Incentive Spirometers are small, hand held devices that that encourage patients who are on pain medicine, or who had recent abdominal or chest surgery, to take deep breath and cough to facilitate movement of secretions, thereby preventing or treating atelectasis and pneumonia. The incentive spirometer was invented in 1970 by R.H. Bartlett and quickly became an inexpensive mode of bedside therapy.

PEP therapy involves having the patient blow through a resistor that applies resistance, or positive pressure (usually 10-20 cwp), during expiration. The pressure acts as a splint to keep otherwise collapsible terminal airways and alveoli open. This facilitates the movement of secretions that would otherwise be trapped due to airway closure. It was invented in Denmark during the 1970s and was became popular in Scandanavia, Denmark and Canada before making its way to the United States. (5, page 1001)

So both IS and PEP therapy were invented during the 1970s and are forms of chest physiotherapy, or chest exercise through manual movement. However, the general concept was conceived of back in 1810 by a doctor by the name of Francis Ramadge.

He was a student of Rene Laennec, the inventor of the stethoscope. The two men worked together in order to find a means of preventing people from developing consumption, the most common respiratory disease at that time.

Laennec suggested a natural cure for consumption was the formation of cicatrizations, or scar tissue, following the softening of the tubercles. This scar tissue, he suspected, acted as a natural barrier against the disease. He suspected most people living with the disease had such scar tissue.

Ramadge, on the other hand, believed that since consumption resulted in a small, contracted and frail rib cage, anything causing the opposite effect prevented consumption. Various other physicians agreed with Ramadge. (1, pages 91- 93) (3, page 8-9, 37)

Two such diseases suspected as acting as natural barriers against the disease, Ramadge suspected, were catarrh (colds) and asthma. He said:

For instance, let us begin with catarrh. Here tumefaction (swelling) of the mucous membrane preventing the free egress of the air, imprisons it in the air-cells, and produces a quasi emphysematous state of the lungs, expanding their entire volume to a certain degree, and pushing outwards in every direction the walls of the chest. Asthma also acts in a similar way. (3, page 8)

They believed if patients took care of their asthma this would act as a barrier to consumption. Ramadge said that this was one of the "ulterior good" effects of having asthma. It was "a lesser evil being substituted for a greater." (6, page 37)(1, pages 91- 93) (3, page 9, 37)

Ramadge also believed that any medical condition that impeded free expiration tended to "mitigate and arrest the disease." Such conditions included: enlarged tonsils, tumors pointing towards the pharynx, polyps in the nasal passages, aneurysms of the aorta, diseases of the heart, obstruction of the liver, hysteria and pregnancy. (3, page 8)

It was based on these theories that he invented what was called "an inhaling pipe," which would later be referred to as the Ramadge Inhaling Pipe. He believed that by inhaling and exhaling through the pipe the patient would develop an expanded chest. In this way, regular use of the pipe had "palliatve and prophylactic, as well as a curative, intentions." (1, page 93) (3, page 10, 59)

It was a pipe with hot tar stuffed into it that you inhaled for therapeutic means. The tar, and the narrow diameter of the tube, provided resistance to inspiration and expiration, and this was supposed to provide "gymnastics" or "exercise" for the consumptive patients.

The Ramadge Inhaling Pipe wasn't exactly PEP therapy, but the principle was similar. He said:

The value of the tube in catarrh, which it supersedes as a curative agent, must not be overlooked. By due exercise and expansion of the bronchial ramifications, it contributes to allay, or indispose to, irritability of the lining membrane, and I have often heard patients state that after its use in the morning they have been better, and more freely able to bring up the accumulated phlegm. (3, page 59)

The inhaling pipe wasn't an IS, although it worked similarly to encourage deep breathing and coughing.

Ramadge said:

The lungs may simply and safely be kept in daily exercise, and expansion to the full amount may be effected by atmospheric inhalation, through the respiratory apparatus. (3, page 15)

Dr. Samuel Sheldon Fitch, in his 1847 book "Six lectures on the uses of the lungs," described the tube. He said: (1, page 91-93)

This tube he at first made about four and a half feet long, with an opening through its whole length, provided with a mouth-piece to go between the lips, and the patient sucked in, or inhaled the air as long as he could, and then through the same tube, blew it out again. By this process, the chest would rapidly enlarge. Dr. Eamadge also made an inhaling tube a little like a whistle, with a valve in it so constructed that the air would go into the mouth and lungs through a large free passage, and on returning, the air would be forced to go outmof the mouth and lungs through a much smaller opening. The effect of which is, to allow the lungs to fill rapidly and without exhaustion of strength, and on leaving the lungs, it is all passed through an opening not much larger than a knitting- needle, by which the air was slowly forced out of the lungs, and by this pressure the lungs were greatly expanded, and the air every where opened the chest in the largest manner. (1, page 93)

Fitch said the tubes were made of wood or ivory, although he recommended they be made of gold, platina or silver so that they last long, and the patient can take the tube wherever he goes and can use it often to keep his lungs expanded. (1,2)

Ramadge said he'd prefer his patients use the inhaling tube...

...but, in the absence of the inhaler, I have no hesitation in saying, on the Principle of choosing the minor of two evils, that exposure to the exciting causes of catarrh, under prudent restrictions, is an alternative that may be judiciously adopted in consumption. (3, page 15)

Surely there were other remedies for consumption, such as leeches, tonics, sedatives and relocation, but...

...The use of the inhaling tube I consider to be essential in the treatment of phthisis; indeed, all other treatment is comparatively secondary and ancillary. (3, page 10)

He said it worked even as a last ditch effort to save the life of a consmptive in the dire states of the disease. He said:

It may be thrown out as a sheet-anchor, even at the eleventh hour. A clergyman's daughter, who had been despaired of, in phthisis, by several medical men, was induced, as a dernier ressort,to employ the inhaling apparatus for two or three months, during which period a decided retrogression of all her bad symptoms was established. Considering herself well, she left it off and died. It is not improbable that, had she gone on till her disease had been more completely brought. (3, page 59)

While recommended for consumptive patients, he said his inhaling device also worked well for asthmatics. He said:

In asthma the windpipe is too small for the volume of the lungs, and, though it may seem contradictory, the mechanical respiration by the tube has the effect of restoring this disturbed relation to its healthy standard. The objection to it, on the score that asthma is liable to be superinduced by its use, arises from idle prejudice. Could I but present one-tenth part of the cases which have been rescued from a premature grave, chiefly by means of using this instrument, I should force irresistible conviction on the most incredulous, or at least induce them to institute a number of experiments, patiently and judiciously, so as to satisfy themselves of the truth. (2, page 10)

Not sold yet as to the efficacy of the Ramadge inhalaing pipe? Well, how about some endorsements that might change your mind. Ramadge said:

This mode of treatment has many advocates, both in England and abroad. Lebeau, physician to the King of the Belgians, and senior surgeon of the Military Hospital at Brussels, as also Hohnbaum, physician to the Duke of Saxe Meiningen, and a distinguished pathologist, highly approve of it. Among the American medical men might be mentioned, the names of Drs. Pitch, Newton, and Hull, of Philadelphia, and several other distinguished practitioners of the same country, together with a great many continental physicians, all of whom have adopted its use, and are its zealous supporters. (3, page 11)

Ramadge would go on to become a well respected physician who specialized in pulmonary disease, ultimately becoming senior physician to the Infirmary for Asthma, Consumption, and other diseases of the Lungs. He claimed to have had the advantage of over 30,000 cases of consumption in all its various stages. He said:

I have no hesitation in asserting -- in contradiction to the opinion of many medical practitioners -- that this disease when properly, judiciously, and skillfully treated, is a curable as any other disease, the curability of which is not dispute. (1, page iv)

The Ramadge Tube was recommended by physicians for pulmonary gymnastics and as a prophylactic therapy for consumption until better devices were invented at the turn of the next century. (4, page 228)

If the profession of respiratory therapy existed in their era, we would be reading their books. However, as it was, their books were written for the medical profession.

Wit and Wisdom

History maketh a young man to be old, without either wrinkles or grey hairs; privileging him with the experience of age, without either the infirmities or inconveniences thereof. Yea, it not only maketh things past, present; but enableth one to make a rational conjecture of things to come. For this world affordeth no new accidents, but in the same sense wherein we call it a new moon, which is the old one in another shape; and yet no other than that hath been formerly. Old actions return again, furbished over with some new and different circumstances. (Thomas Fuller in the Epistle Dedicatory to his The History of the Holy War, March 6th, 1639).
